I have read many of the discussions regarding dx58so boot-up issues but mine appears to be a bit different.
Issue
---------
I wanted to upgrade the BIOS via the USB method (Desktop Boards — Instructions for Recovery BIOS update), so I followed the steps given in that doc. I removed the jumper as given in url (above) so that the bios recovery is triggered, but that didnt work (no video, no beep, nothing). I waited for 15min or so and shutdown the machine. I replaced the jumper to normal and then started up again, but again no video, no beep.
I purchased a POST card and plugged that into the system to see any indication of an error and all I can see is 03 code. The intel manual do not help in understanding the post code but my guess is that the bios is somehow corrupted. I have tried many things suggested in various blogs/discussions and still clueless on the real problem (Ex. remove all mem and go to basic config to boot or use the jumper in config mode, etc). The system was working earlier, just that my hard-drive crashed before I embarked in upgrading the bios.
Is there a known issue in bios recovery? I purchased the board in 2010 so the bios should be during that time. Any pointers would be of great help.t_g
